74F676 16-Bit Serial/Parallel-In, Serial-Out Shift Register
74F676
16-Bit Serial/Parallel-In, Serial-Out Shift Register
General Description
The 74F676 contains 16 flip-flops with provision for syn-
chronous parallel or serial entry and serial output. When
the Mode (M) input is HIGH, information present on the
parallel data (P
0
–P
15
) inputs is entered on the falling edge
of the Clock Pulse (CP
) input signal. When M is LOW, data
is shifted out of the most significant bit position while infor-
mation present on the Serial (SI) input shifts into the least
significant bit position. A HIGH signal on the Chip Select
(CS
) input prevents both parallel and serial operations.
